Scamalot Advice
If you see this advertised online or receive an unsolicited email about it, remember that the NCSC doesn't sell products or hawk gadgets ΓÇö they publish guidance, full stop. Anyone trying to flog you "NCSC-engineered" hardware is lying, and that alone tells you everything you need to know about them.
Stop and think before you act. If something feels urgent, threatening, or too good to be true ΓÇö that urgency is the weapon. Scammers use pressure to override your judgement. Nothing is ever so urgent that you can't take five minutes to check, call back on a number you found yourself, or ask someone you trust.
